haha looks like i might just be a sucker for buying buggered turbos then. What you said does make sense. Just make sure you buy a good turbo that spins freely i guess. Whats the most fuel pressure people have run on a needle and seat and what carb? As a budget approach running standard 7psi boost would there be a carb/ needle and seat cabable of holding 10psi fuel pressure negating the need for expensive rising rate regulators and fuel pumps/return line etc in a blow through design. If a new gasket kit is put through the carb and sufaces are flat they should seal ok with just a hat and lowish boost.
